Question

1. A study was created to test the effects of jazz on people's sleep patterns. The hypothesis of the

experiment was that if people listened to jazz music as they fall asleep, they will sleep for longer

periods of time. For the experiment, 2 groups of people were created. One group was placed in a

quiet room where they went to sleep and they were timed on how long they slept. The other

group was placed in a room where jazz music played softly as they began to sleep and played

throughout the night. As each group awoke, their sleep times were monitored.

What is the dependent variable in this experiment?

Answer 1

The correct answer is -

The dependent variable - Sleeping time or amount of both test groups.

Step-by-step explanation:

In this experiment where the effect of jazz music on the sleeping pattern of people is being tested. For this study, there are two test groups, a control group with a quiet room and an experiment group with slow jazz music during their sleeping and monitored the time when both groups of people sleep.

So, the independent variable is slow jazz music here which is affecting the sleeping amount of time people sleeping, so the dependent variable is the time people sleep
